What Are the Cupping Steps in Specialty Coffee?

Ever wondered how professional roasters and buyers decide which coffee beans to buy—or which ones you’ll love? They don’t guess. They cup. Cupping is the standardized method used worldwide to assess green coffee quality, roast development, and flavor potential. If you’ve ever asked whether coffee can be sweet, tangy, or even addictive, cupping is how you find out for yourself.

The cupping process uses 10 grams of coffee beans and 180cc (milliliters) of boiling water, ground to a medium-coarse level between French press and pour-over. After a 3-minute soak, you break the crust, smell deeply, and taste to identify sweetness, acidity, and more.

What Is Coffee Cupping?

Cupping isn’t just sipping coffee—it’s a structured evaluation method. It’s the go-to technique for roasters to understand a coffee’s inherent traits before roasting, and for blending different beans into a balanced profile. More than a tasting, it’s how the coffee industry communicates flavor objectively. If you’ve heard that coffee has sweetness or subtle fruitiness, cupping helps reveal those notes clearly.

Why Cupping Reveals True Coffee Flavor

Unlike brewed coffee—where filters, ratios, and techniques shape the cup—cupping strips everything down. No paper filter, no pouring method, no milk. Just ground coffee and hot water. That makes it the purest way to experience origin character, roast level, and processing method. It’s how experts determine if a coffee is bright, sweet, heavy, or delicate. And yes, it’s how they confirm coffee really does have a natural sweetness.

How to Cup Coffee: Step-by-Step

To cup like a pro, follow these exact steps:

• Grind Size: Grind the coffee to a setting between French press and pour-over—medium-coarse, the norm for cupping.
• Dose & Water: Use exactly 10 grams of coffee and 180cc (about 6 fluid ounces) of freshly boiled water.
• Bloom & Pour: Add hot water directly over the grounds. Let it bloom naturally; the grounds will float briefly.
• Steep Time: Let the coffee steep for 3 minutes without disturbing it.
• Temperature Drop: After 3 minutes, the brew cools to around 70°C—a perfect range for evaluating aroma and taste.
• Breaking the Crust: With a spoon, gently break the floating coffee grounds on the surface. As you do, lean in to smell the deep aromas released.
• Skim & Taste: Remove the remaining grounds and oils from the surface. Then, taste the coffee directly from the cup using a spoon. Slurp lightly to aerate and spread the liquid across your palate.
• Evaluate: Identify flavor attributes—look for sweetness, acidity, body, and aftertaste. Compare what you taste to familiar sensations to help remember the profile.

Key Ratios and Measurements in Cupping

Cupping follows precise metrics to ensure consistency:

• Coffee to Water Ratio: 10g coffee : 180cc water (approximately 1:18)
• Grind Consistency: Between drip and French press—medium-coarse
• Water Volume: 180 milliliters per 10 grams of coffee
• Steeping Duration: 3 minutes
• Tasting Temperature: Around 70°C after cooling

Frequently Asked Questions

What is coffee cupping and why is it important?

Coffee cupping is a standardized method used by professionals to evaluate the flavor, aroma, and quality of coffee beans. It’s essential for roasters to assess roast profiles, for buyers to select beans, and for creating blends. It reveals inherent traits like sweetness, acidity, and body without the variables of brewing methods.

How much coffee and water do you use for cupping?

Use 10 grams of coffee and 180cc (about 6 ounces) of boiling water per cupping bowl. This 1:18 brew ratio ensures enough strength and clarity for flavor assessment.

What is the correct grind size for cupping?

The grind should be medium-coarse—roughly between French press and pour-over grind settings. This allows for proper extraction during the 3-minute steep and easy removal of the crust.

How long should coffee steep during cupping?

Coffee grounds should steep for exactly 3 minutes. After that, let the temperature drop slightly to around 70°C before breaking the crust and tasting.

Do you remove the coffee grounds before tasting?

Yes. After the 3-minute steep, you break the crust with a spoon, smell the aromas, then skim off the floating grounds and oils before tasting the liquid directly.

What flavors can you detect through cupping?

Cupping helps identify a wide range of flavors including sweetness, fruit acidity, bitterness, body, and aftertaste. It’s one of the best ways to notice subtle notes like caramel, citrus, or nuttiness that might be hidden in regular brewing.
